I recently learned from Tyler Cowen's superb book Discover Your Inner Economist that people are sometimes more rational about choice when it concerns other people. He states, "The more personal the choice, the more likely that fear drives out reason" (page 129). For example, people make more rational choices about whether to take a vaccine when making the choice for others than themselves.
